[Robot Tries To Escape From Children’s Abuse]

A robot patrolling in a shopping mall [often] attracts attention, in particular children’s. When requested to open the way, in most cases the children soon step aside. However, in some cases the children ignore the requests and persistently hinder the robot.

This happens more often if there are many children around, and if no parents or adults are present. Occasionally the children’s behavior escalates and becomes violent.

We observed kicking…

even throwing objects on the robot.

We developed a simulator of pedestrian behavior. It includes the simulation of children’s behavior and a model of probability of abuse.

Robot

Child and its abuse probability (increasing in time)

Other child with parent approaching

Abuse probability increases when more children are present

Simulations allow the robot to predict the children’s behavior and abuse situations, which is used for planning

When simulations predict a high abuse probability, the robot changes its original destination. Here it chose to stay close to the child’s parent, as this lowers the possibility of abuse. Using simulation-based planning resulted in a significant decrease of abuse cases in our tests.
